INC., 0F NEW YORK, N. Y., A CORPORATION OIE NEW YORK RAZOR-BLADE srRorrER Application filed October 10, 19.25.r Serial No. 61,693.

rIhis invention relates to improvements in devices for holding razor blades during stropping.

One of the objects of this invention is to provide a device of this type in which the handle and blade holder are formed integrally in two elements'which lare vhinged together, and are provided with members to hold the two elements in predetermined relation to clamp the blade and hold it securely during holder by being thestropping operation'.vv

Another Objectis to provide a guard for the blade which is held in positive and fixed relation with regard to longitudinal and transverse movements in respect to the blade securedlto one ofthe elements, but is aiflorded a certainA limited pivotal movement with regard to the elements to permit the successive stropping of two faces of the razor blade.-

Another object is to construct such devices in a simple and cheap fashion, of few parts, easily manufactured and assembled, and having structural strength without encumbrance.- I

' With these and othery objects in view, as

, will appear in the course ofthe following specification and claims,this' invention has been illustrated in several modified forms `on the accompanying drawings, in which:

Fig. 1 is a plan ofsucha device in the closed position, with a razor blade therein ready for stropping. f Y

Fig. 2 is a similar plan, but with the .device openfor the insertion or removal of a razor blade. i

Y Fig. 3 isa section on on an enlarged scale.

Figs. 4 and 5y are sections on lines 4-4 and 5 5, respectively, of Fig.y 1, ony the same enlarged scale. f

Fig. 6 is a plan view of a modified form of line 3-'3 of Figpl Y the invention, in the closed position.

Fig. 10 is a perspective view of the guard i utilized in the modified form of Fig. 9.

Fig. 11 is a section on line 11-11 of Fig. 9,

onV an' enlarged scale.

In the form of construction shown in Figs.

1 to 5 the blade vholders 10 and 11 are coni nected together by a hollow rivet 12 employed as a pivot, whichpermits the two holder members to swing with regard to each other while remaining in approximately parallel planes.' The metal ofthe holder members is bent outward in forming, as upon a punch press or the like, as shown in Fig. 3, to formA cups through which the rivet passes, while the rims ofthe cups are in substantial contact, as indicatedat 13 in `this figure, to aiford a large area of contact and assure long life to the instrument. holder members has a further outward bend 14 to form a passage 14a transverse of thev holders when the two are brought into clamping relation. The metal of the holder members is thereafter bent inward and the two members runin substantial parallelism and close together, so that they may clampV a razor blade between themselves, one of the The metal of the" members, 11, forV this purposehaving the studs 15 formed thereon to enter lthe usual apertures in a double-edged blade to assure the same against transverse or longitudinal movement in the blade holders. Beyond the position occupied by the razor blade the metal of the holder members has another outward bend and return, at 16, form a passage 16a when the holder members arepin the clamping position to the passage at 14a.

The holder member 10 is shorter than the member 11. The member 11 is rebent at its end 17 and folded back upon itself, to end at 18, in approximate abutting relation with the end of the holder member 10. A tubular sleeve 19 is mounted over the folded end of the member 11, and carries inwardly a pin 20 which projects into a slot 21 formed in this member 11: the slot limits thesliding movement of the sleeve A19 with regard to the members 1() and 11, but permits the sleeve lto be withdrawn from embracing the member 10.

lOll

A guard is fastened permanently to the 'holder member 11 by means of rivets 22 and 23, as shown in Figs. 2, 3 and 4. This guard Ception Vof the rivets 22 and g The aper-v tures are larger than the rivet shanks, and

Ythe rivets are of such dimensions that the Vtransverse bars mayyrock aboutl and slide uponl the rivets, and present the side bars v24, and 25 on oppositey sides of the edge of the razor blade B mounted in the holder 'Y members, as shown by dotted lines in Fig. 5.

It is preferred, for strength and `for compactness ofconstruction, to arch the bladereceiving portion of the blade holders, as shown at 30l in Fig. 5.V f

v The'operation of this device is as follows: lVith the parts inthe opened posit-ion. of Fig. 2, a double-edged razor blade is placed loosely upon the studs 15, and the upper and shorter holder member 10 is swung about the pivot- 12 until it lies Vparallelto and in close proximity to the longer member 11, the sleeve 19` having been vmoved to the position shown in this figure. When the end of the member 10 and the rebent end 18 of member 11 are in alinement, the sleeve 19 is forced inward over the end ofV they member 10 tosecurely clamp the blade in position. f lVhile the blade isheld against movement, yet the guard may .roch freely for a limited distance in the pasv sages described above, but is restricted in this movement by the sides of the holder members.

The device is now ready for use. The sleeve forms an excellent handle,`and 'the device is drawn back and forth vover ,a strop,

reversing atreach end of a stroke, by rocking Y the blade over its edge. The strop cannot be out during this reversal, since the side bars 22, 23 of the guard hold the blade edge'aivay from the strop. Y Y

After stropping is Vfinished, thesleeve 19 is pulled bach, the holder member 10 svvung around into the position shown in Fig. 2, and the razor bladeflies free and may be easily removed for insertion in a razor frame.

During the stropping the guard rocks` to alternate sides of the edge of the blade, as shown in dotted lines in Fig. 5. f

In the modified form of Fig. 6 the elements in general are the same as in Fig. 1, except that the holder members 30, 31 are formed integrally, and are merely rebent at the handle end, as at 30a, and a sliding clip 33 fits over the two' holderV members at the bladerend.r The same transverse passages 14a .and 16FL are provided for the reception of the guard, which isagain composed of the side ybars 24,25 and the transverse bars 26, 27,

and are held by rivets 22, 23.` The clip 33 may beprovided with a pinand slot arrangement, so that the clip cannot become detached from one of the holder members; the clip 33 for this purpose has a rivet 34 thereonr u 7) which engages inthe slot 35 in the member 31.

In the modified form of Fig. 8 the holder members are again of separate pieces, joined together by a transverse pivoting arrange- Amember 41 has a slot 41a of uniform Width therein toV receive the' shank of-a krivet 44 which is held in a sliding bloclr45 this block slides in the'member 41', and is guided therein by its upcurled lat-eral edges. The block carries a further rivet'46 with an enlarged head 47 which may pass through the enlarged end 48 of a slot 49',V but is prevented from `passing 'through the slotv 49'itseli?. rIn this lWay, by sliding the bloclr 45 lengthwise of the holder members, the latter may be locred rigidly together. The operation of this device is the same as that of :F ig. l, exceptl that openingthe sliding block the'tvvo holder members open like theleaves of a book. l .v The Vform shown in Figs. 9, 10 and 11 is substantially the same as those already described in Figs. 1 to 5 With the holder niembers 50, 51 he ving pivot 52 and passages'l4a, 16, but a slightly different construction is indicated for the guard, which isV kformed of a single piece -of Wire four sides 54,l 55, 56, 57 andV Welded' Orsoldered together at 53.v The parts of the transverse sides 55, 57,' Which are kto enter the channelsat 14, 16, are squeezed down 'at 59, 60 to flatten them and lthen perforated, as shown at 61,. k62, for the reception of the rivets 63, 64. These rivets 63, 64 have the collarsv 65 at their bases tohold the guard in 45 is used, and

bent to' form vthe Y CSH- tral position inthe channels at 14', 16.v Any' position upon the blade; and the operation of this device is the same as that shown in Fig. 1.

It is Vobvious that the invention is not restricted to the particular form or forms shown, butthat any `Vmodiiications may be made therein Withinthe scope of the appended claims. f v I claim: 'l p' 1. In a razor blade holder forl use during stropping, a pair of holder members, means to hold said members permanently together and permit their relative movement into blade-clamping and blade-releasing positions, means to secure said holders in blade-clamping position, bent portions Jformed in said f members to present an open transverse passage between said members in the clamping position thereof, and a transverse bar loosely held in said passage and in permanent attachment to one of said members in the Clamping position thereof, a side bar supported by said transverse bar opposite the edge of a` razor blade clamped in said members, and means to hold said side bar in parallelism with the edge of the .razor blade.

2. In a razor blade holder for use during stropping, a pair of holding-members, means to hold said members permanently together and permit their relative movement into bladeclamping and blade-releasing positions,

means to secure said holders in blade-clampy ing position, bent portions formed in said members to present open transverse passages y between said members at each end of a razor blade clamped in said members, transverse bars in said passages and held in permanent relation to one of said members, side bars Xed to and supported by said transverse bars in parallelism to the edges of a razor blade clamped in said members, said transverse bars and the walls of said passages cooperating to limit the swinging movement of said side bars to opposite sides of the edges of the blade during the stropping operation.

3. In a razor blade holder for use during stropping, a pair of holder members held in permanent relation to each other and adapted to have relative movement into bladeclamping and blade-releasing positions, means to secure said members in blade-clamp- 420 ing position, bent portions in said members Y to :form transverse passages between said members in such clampingposition, and a guard formed of integral side bars locatedy in parallelism to the edges of the razor blade .f clamped in said members, and transversebars permanently attached to one of said members and located in said passages'in such clamping position, said guard having a limited permissive rocking movement with regard to said 59 members to disclose the edges of the blade at either side of the stropping operation.

In testimony whereof, I aX my signature.
